I must be tired but I'm still confused about the issue.
Below is the code you've posted slightly modified to search all the 
mounted volumes until a match is found.
At my side, it works in plain vanilla Mac OS 9.2.2 under Carbon.
I'm not running OS X, so perhaps you could test and report back.

_FactSrvrType    = _"APPL" // File type code
_FactSrvrCreator = _"CCPr" //Creator code

'~'2
// buffer for CatSearch code in fn CCLocateFile.
_FactBuffSz     = 2048 // seems plenty (was 32768)
dim gFactCatSrchBuffer.FactBuffSz// see IM File Manager PBCatsearchSync

end globals



clear local
local fn CCLocateFile( type as OSType, creator as OSType, theFSSpec as 
ptr )
// Find 1 occurrence of file of specified type & creator.
// If found, return _noErr, with the file's FSSpec filled in; else 
return error code
